connie poured 200 milliliters of juice into a glass from a juice carton. She then poured 225 milliliters into a second glass. What is the final change in the volume of the carton?
Answer:
A reduction of 450ml
Step-by-step explanation:
Given
[tex]V_1 = 200ml[/tex] -- To glass 1
[tex]V_2 = 250ml[/tex] --- To glass 2
Required
The final change to the carton
To do this, we simply add V1 and V2
So, we have:
[tex]Total = V_1 + V_2[/tex]
[tex]Total = 200ml + 250ml[/tex]
[tex]Total = 450ml[/tex]
This implies that the changes is a reduction of 450ml

its diameter. What is the volume of the
teepee? Use 3.14 for .
The volume of the given cone is 718.01 square feet. Therefore, option H is the correct answer.
What is the volume of a cone?The volume of a cone is the amount of space occupied by a cone in a three-dimensional plane. A cone has a circular base, which means the base is made of a radius and diameter. The volume of a cone formula is 1/3 πr²h.
Given that, radius of a base of cone is 7 feet.
A height of a cone equal to its diameter = 7×2 = 14 feet
Here, volume of a cone = 1/3 ×3.14×7²×14
= 718.01 square feet
Therefore, option H is the correct answer.

63.7 would Be the correct answer
Step-by-step explanation: Below Is Info About How to Calculate Precentage UwU
how to calculate percentage of a number. Use the percentage formula: P% * X = Y
Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.

Answer: 4
Step-by-step explanation:
4^2=16
Answer:
4
Step-by-step explanation:
When we square something we just multiply it by itself.
2 x 2 = 4 so not 2
3 x 3 = 9 so not 3 either
4 x 4 = 16 this one is correct!
8 x 8 = 64 not this one either

Carl buys seven 5-gallon jugs of water for the water cooler. How many liters of water did Carl buy? (1 gal= 3.785 liters)
Answer:
Carl buys 132.475 liters of water.
Step-by-step explanation:
Since Carl buys seven 5-gallon jugs of water multiply 7 by 5 to know how many gallons of water Carl bought in total.
7(5) = 35 Gallons
Now that you have the total amount of gallons of water Carl bought you have to convert 35 gallons to liters given that 1 gallon = 3.785 liters by multiplying 35 by 3.785.
35(3.785) = 132.475
So Carl bought 132.475 liters of water.
Though that is the answer based on what is given a gallon is actually equal to 3.78541 liters so the exact answer would be 132.489 liters of water.

A swimming team has 16 members. The coach wants to create teams of 4 swimmers to compete in the relay race. How many different teams of 4 can she make without repetition?
There is 1820 ways of teams of 4 can she make without repetition using combination formula.
What is combination?
Selections are another name for combinations. The choice of items from a predetermined group of items corresponds to combinations. We don't want to organise anything here. We are going to choose them. We use the notation nCr to indicate how many distinct r-selections or combinations there are among a set of n objects. A combination is distinct from an arrangement or a permutation. No matter how the objects are arranged, combinations are produced by choosing some or all of them.
Here There are 16 total swim team members and 4 swimmers that will be chosen for each relay team.
So, n=16 and r=4. Then
=> nCr = [tex]\frac{n!}{r!(n-r)!}[/tex]
=> 16C4 = [tex]\frac{16!}{4!(16-4)!}[/tex]
=> 16C4 = [tex]\frac{16!}{4!*12!}[/tex]
=> 16C4 = [tex]\frac{16*15*14*13}{4*3*2*1}[/tex]
=>16C4 = 4*5*7*13 = 1820
Hence there is 1820 ways of teams of 4 can she make without repetition.

Find the value of the expression below when x = 27, y = - 4 , and z = 64 . 2 * root(3, x) - 5sqrt(x) + y ^ 2 answer
Answer:
-18Step-by-step explanation:
x = 27, y = - 4, z = 64Expression:
2∛x - 5√z + y² = 2∛27 - 5√64 + (-4)² = 2(3) - 5(8) + 16 = 6 - 40 + 16 = -1814. Which of these functions is not linear?
A) y=x^2-x
B) y=1-x
C) y=x/3
D) y=2/3x-2x
Answer:
A) y = x²- x
Step-by-step explanation:
A linear function will have y equal to x, without x being manipulated by a square root, exponent, etc.
y = x²- x has x being squared.
This will create a graph of a parabola, which is not linear.
So, since it is a quadratic instead of a line, answer choice A) y = x²- x is correct.
Use the difference quotient of A(r)= πr2 to calculate the average rate of change during certain intervals.
The difference quotient of A(r) is:
StartFraction pi (r + h) squared minus pi r squared Over h EndFraction = StartFraction pi (r squared + 2 r h + h squared) minus pi r squared Over h EndFraction = StartFraction pi r squared + 2 pi r h + pi h squared minus pi r squared Over h EndFraction = 2 pi r + pi h
